Turning now tov themannerinvwhich the Y tension members -12 arefconnected,'the reference lnumeral 21 indicates aplurality of` bolts which secure the'Y upper extremities of the vmembers to the bumping block 10. For an understanding kof. the manner in which the lower extremities of the tension members are secured to the running rails 14 of they, track attention is respectfully Yinvited to a consideration of Figure Brin conjunction with 'Figures 1 and 2. As therein illustrated, ya

Aclamping plate 24 extends lengthwise forfa short distance of the .running rail 14 andfis i 'firmly'secured thereto by means of bolts 26 which lextendV through apertures in the run ning'rail14 and are seated upon an anchor plate 27 located on the outer side of the rail V'14.V The anchor plateis of approximately the :same length as the clamping plate 24 and to# gether the two parts cooperate in forming an extremely rigid and durable connection. Extending inwardly froni the clampingplate 24 is an'integrally formed connecting arm 23 Ywhich is so shaped relatively to the clamping plate 24v as to extend upwardly in the same direction'asthe tension member 12. 'The con- ,V necting arm 23'is suitably and rigidly'secured fregivenitfwill be appreciated that the i 'the/tension 1and compression members vwhich lin turnj'are rigidly' connected tothe running rrails 14. c In spite of the rigidity of the con- ;struction so far described, it has been yfound that when a severe blow is imparted to the yblock V10, Vthere is' a'jtendency 'on' the part of the lower extremities of the tension member .12 to vmove suddenlyV inward toward one another thereby exerting a buckle action upon the Vrunning jrailswhich tends tov displace themfroin their proper positions. Inv order Vefl'icient'lyto overcome lthis tendency the' presenty invention contemplates the provision' vof means for Vadequately resisting suchstrains and as illustrated herein the said means comiprises a bracing rod 29 vwhich extends beneath v V'the baseflanges ofthe Yriiniiinggrails andpasses through'` aperturesfformed in the down-v ,w'ardly projecting extremitiesof the tension Y -'member`sj12"( Figure 31) In order to hold the "bracing rod '29 in close contact Vor engage- 'inentwith the base flange of the running rail,

Yas shown;y in -Figure 3, thereis provided a ,T

drawing member 30 h aving an Afiippe'r Qinwardly: extending cam-like portion which 7 v @verliestheouteriedgeV ofthe vbase flangef'of the running rail. 'Nuts 31 are :provided for 4holdingthe'drawing member in'place andit "willf be appreciated vfrom y an inspection of and as illustrated such `means takes the'form 'of la spacer pipe-32 whichclosely 'surrounds bers 12.. Thus, in 'use any tendencyon the Y a pair of bars straight throughout theiren-y Figure 3 that in applying the nutsand drawing member, lthe ,latter during'the course ofV its application presses, or draws, the bracing bar 29 firmly and tightly into` engagement with the base flange of the running rail 14. Notonly ydoes the drawing member '30 serve toy draw theA bracing bar into proper position during assemblage ofthe device, but it also serves to hold the bar in proper position: during use. The bracing bar Yalonefwiill not,`of 7 course, resist any tendency of the'V rails 14 to buckle, or collapse, inwardly when wa tremendous blow is impartedto the bumping block 10, but the invention. contemplates the-employment of means for resistingV this tendency the bracing bar 29 and extends between the opposite 'inner web faces ofthe tension memp-art of the Vlowerextremities ofthe tension membersto'move toward one another is adequately resisted and overcome; by meansA of the spacer'82.y It must be'recognize'd, however, that devious kinds of spacing members and means may be employed and that the `invention is in no wise limited tothe exact form illustrated in the-drawings.
